Sense Relief App™ uses acupressure to quickly and effectively relieve your nausea and vomiting symptoms associated with morning sickness and motion sickness. The acupressure is delivered through the Apple Watch’s Taptic Engine and Sense Relief’s nerve stimulation technology. The App applies pulsating acupressure on the underside of the user’s inner wrist, to stimulate the P6, or Nei-Kuan, nerve acupoint.
